The 48 items in the scale has been gathered in 7 factors without constituting a logical problem. These factors were named as General Statistics Skills (Cronbachalfa = 0,93), Research Skills (Cronbachalfa = 0,88), SPSS Skills (Cronbachalfa = 0,85), Time Management and Lecture Study Behaviours (Cronbachalfa = 0,82), Computer Usage Skills (Cronbachalfa = 0,79), Mathematics Skills (Cronbachalfa = 0,74) and Lecture Listening Skills (Cronbachalfa = 0,81). As a result, the scale has been identified as reliable for usage to evaluate the teacher trainees’ self-efficacy towards statistics and some suggestions were offered.
